APPARATUS FOR COOLING WATER.

Application filed October 28, 1924, Serial No. 746,271, and in Germany November 5, 1923.

My invention relates to improvements in apparatus for cooling wateryand more particularly in apparatus for cooling large volumes of water, such for example as the cooling Water of condensation plants. The object of the improvements is to provide a system which requires little space and which is economical in operation, With this object in view my invention consists in distributing' the hot water in the form of a thin film on the inner wall of a rotating receptacle, and thereafter ejecting the same into a cooling chamber located around the said receptacle and traversed by a current of air.

For the purpose of explaining the invention an example embodying the same has been shown in the accompanying drawing in which the same reference characters have been used in all the views to indicate corresponding parts. In said drawing,

Fig. 1, is a vertical sectional view of the apparatus, and

Fig. 2, is a sectional View taken on the line 2--2 of Fig. 1.

Figs. 3 and 4 are vertical sectional views showing certain modifications.

In the example shown in Fig. 1 my improved cooling apparatus comprises an outer casing k open at its top and provided at its wall with an annular set of rods or projections 6 adapted to distribute the water falling thereon. Within the casing is a cylindrical open topped receptacle 6 is mounted which is formed at its bottom with a tubular extension or shaft a guided in a bearing 9 and carrying a belt pulley z for imparting rotary movement to the receptacle 6. At its top the receptacle 6 is guided in a crosspiece 7" secured to the wall of the casing is. The tubular shaft a communicates with an inlet pipe 6 adapted to supply the hot water to the rotary receptacle 6. At its outer wall the receptacle 6 carries wings f disposed angularly of the axis of the receptacle and providing a fan for drawing a current of air in upward direction through the chamber a, and near its top it is provided with perforations d. In some cases I provide the wings at the top of the receptacle and above the set of fingers e. A vertical disposed annular rim of flange g, the upper edge of which is slightly above the discharge level of g, is provided at the bottom of the-casing Is, for collecting the cooled water. The casing is is provided near its bottom with discharge passages 9 through which the water flows into the receptacle h from which it is returned to the condensers. I The rotary receptacle 6 is provided with air admission pipes m opening near the axis pf the receptacle, so that the water has no access thereto. Preferably the outer ends of the sald pipes are curved forwardly and in the direction of the rotation of the rece tacle so as to actin the manner of hue ets taking in the air from the vessel is and de- 11ver1ng the same into the receptacle 6. In a modification of the apparatus as shown in F 1g. 4 I supply the air through a pipe disposed axially of the receptacle. For example the air may be supplied through the hollow shaft 8 extended upwardly into the inner or an space of the receptacle, the water being supplied through a pipe 6 through which the tubular member 8 passes, the pipe e opening into the receptacle I) at the bottom thereof as previously described.

The operation of the apparatus is as follows: The receptacle 6 is rapidly rotated, and the hot Water is supplied thereto through a pipe 6 and the hollow shaft a. By centrifugal action the water is distributed on the inner wall of-the receptacle in the form of a thin film which, due to gravity, would be somewhat thicker at the lower part of the rotary receptacle. When thus flowing through the receptacle 1), the water is cooled by the current of air flowing along the outer face of the receptacle and by the air admitted through the pipes on or the pipe 8 as the case may be. From the top part of the receptacle 6 the water is thrown in a state of fine distribution into the chamber n;

it falls downwardly and is further distrib-- uted by the rods or projections e. The air escapes from the inside of the rotary receptacle through the open top thereof, as shown by the arrows in all. of the figures of the drawing. The wings f or f acting as a fan produce a current of air in upward direction and through the chamber 72, by means of which the water moving downwardly through the casing 70 is further cooled. The water delivered through the discharges g and collected within the tank It is sufliciently reduced in temperature to be again used for cooling purposes.

From the foregoing descri tion it will be understood that by means 0 my improved apparatus large volumes may be cooled on a comparatively small space, in a very efi'ective Way, and within a minimum of time. Further the cooling effect may be regulated within .broad limits by varying the number of revolutions of the receptacle b and the supply of coolin air.

hile in escribing the invention reference has been made to a particular example embodying the same I wish it to be understood that my invention is not limited to the construction shown in the drawing, and that various changes may be made in the general arrangement of the apparatus and the construction of its parts without departing from the invention.
